f19f04f549 cmd/present: adjust article presentation
* Give the article title a larger, heavier font than any heading.
  It was strange that the title was 20px regular while the
  h1 section headings were 24px.

* Move the author attribution to the top of the page.
  Author at the bottom, like a signature, may make sense for blog posts,
  but I think it makes less sense for articles.

* Fix the spacing around author lines. Each author line is a <p>
  and the intent seemed to be to cut the vertical space between them
  but that wasn't working.

* Give the table of contents a title, to make clearer what it is.
  Do not show table of contents in printouts.

8e53eb937b go/ssa: support custom TestMain functions in test packages
Supporting user-defined TestMain functions requires that we generate a
"testmain" package for each testable package, rather than a single one
for the entire program.  This entails these API changes:

1. (*ssa.Program).{CreateTestMainPackage,FindTests} both now
   accept only a single package.  Existing clients that pass them
   multiple packages must call them from a loop.

2. (*ssa.Program).FindTests returns an additional result, the the
   optional TestMain *ssa.Function.  Existing clients may discard it.

Also:
- Test the new logic using the SSA interpreter
- add ssautil.MainPackages helper
- callgraph: allow multiple main packages, and analyze them all
- ssadump -run: allow multiple main/test packages, and run each in a new interpreter
- minor simplifications to some callers (e.g. guru)

053ddb97bf x/tools/cmd/heapview: add basic client serving
This change primarily exists to import Typescript and the
ES6 module loader polyfill as dependencies for this project.
Both dependencies are relatively lightweight and can be easily
removed if we decide we don't need them.

The module loader polyfill implements support for an upcoming
browser feature in ES6 (the next version of JavaScript). This
feature helps modularize Javascript code and conveniently split it
into multiple files. It should be supported by the stable versions
of the four major browsers (Chrome, Firefox, Safari and Edge)
by the end of the year. Once that happens, we can remove the polyfill.

The Typescript compiler provides two things: First, it compiles
new, but not-yet-supported ES6 Javascript features into ES5. It
also provides a typechecker similar to what Closure does, but types
are indicated in syntax rather than JSDoc comments. If we decide
we don't want this dependency, we can compile the Typescript code
into human-readable JavaScript code. (The compiler basically
strips out types and replaces ES6 language features with more
well-supported JavaScript equivalents). The Typescript compiler
is not required for development. typescript.js and a feature in
the module loader will be used to compile Typescript into JavaScript
at serving time. (We might want to do something different for the
production version, but we can get to that later).

The change also adds code to serve the HTML and Javascript files.

edf8e6fef8 cmd/goimports, imports: optimize directory scanning and other things
This brings goimports from 160ms to 100ms on my laptop, and under 50ms
on my Linux machine.

Using cmd/trace, I noticed that filepath.Walk is inherently slow.
See https://golang.org/issue/16399 for details.

Instead, this CL introduces a new (private) filepath.Walk
implementation, optimized for speed and avoiding unnecessary work.

In addition to avoid an Lstat per file, it also reads directories
concurrently. The old goimports code did that too, but now that logic
is removed from goimports and the code is simplified.

This also adds some profiling command line flags to goimports that I
found useful.

e047ae774b cmd/goimports, imports: make goimports great again
I felt the burn of my laptop on my legs, spinning away while processing
goimports, and felt that it was time to make goimports great again.

Over the past few years goimports fell into a slow state of disrepair
with too many feature additions and no attention to the performance
death by a thousand cuts. This was particularly terrible on OS X with
its lackluster filesystem buffering.

This CL makes goimports stronger, together with various optimizations
and more visibility into what goimports is doing.

* adds more internal documentation

* avoids scanning $GOPATH for answers when running goimports on a file
  under $GOROOT (for Go core hackers)

* don't read all $GOROOT & $GOPATH directories' Go code looking for
  their package names until much later. Require the package name of
  missing imports to be present in the last two directory path
  components.  Then only try importing them in order from best to
  worst (shortest to longest, as before), so we can stop early.

* when adding imports, add names to imports when the imported package name
  doesn't match the baes of its import path. For example:
        import foo "example.net/foo/v1"

* don't read all *.go files in a package directory once the first file
  in a directory has revealed itself to be a package we're not looking
  for. For example, if we're looking for the right "client" for "client.Foo",
  we used to consider a directory "bar/client" as a candidate and read
  all 50 of its *.go files instead of stopping after its first *.go
  file had a "package main" line.

* add some fast paths to remove allocations

* add some fast paths to remove disk I/O when looking up the base
  package name of a standard library import (of existing imports in a
  file, which are very common)

* adds a special case for import "C", to avoid some disk I/O.

* add a -verbose flag to goimports for debugging

On my Mac laptop with a huge $GOPATH, with a test file like:

	package foo
	import (
	       "fmt"
	       "net/http"
	)

	/*

	*/
	import "C"

	var _ = cloudbilling.New
	var _ = http.NewRequest
	var _ = client.New

... this took like 10 seconds before, and now 1.3 seconds. (Still
slow; disk-based caching can come later)

50ff896a1c cmd/guru: definition: opt: avoid type checker for qualified identifiers
For a 'definition' query on X in p.X, use special logic to load and
parse package p and find the declaration of package member X, without
using the type checker.  Such queries now typically take under
10ms (faster than godef).

The logic assumes that import "something/p" defines the name p.  If this
assumption is false, p.X could be a selection of a field or method X on
a member p of the same package, defined in another file.
So don't write code like that.

Added missing test of 'definitions'.
JSON tests now sanitize absolute $GOPATH filenames in the output.

Fixes issue #15458

9ae7e1769c cmd/guru: Emacs: run guru asynchronously using compilation-mode
We define a derived mode of compilation-mode, so that various
names say "guru" instead of "compilation", and use the hooks it
provides to apply our postprocessing incrementally instead of
all at the end.  It's much faster, and works nicely with the
new streaming referrers query.

Compilation mode requires a shell command, not an execve array,
so go-guru--compile-command joins the arguments with spaces.
go-guru--exec has been specialized for JSON mode,
and renamed to go-guru--json.

go-guru--set-scope-if-empty is now done by each mode, to avoid
the NEED-SCOPE parameter to go-guru--exec.

- sameFile first attempts a simple comparison of path.Clean'ed paths.

2da0720e4f cmd/guru: support streaming plain and -json output
Visible changes:
- "referrers" queries now emit a stream of results,
  so they start appearing quickly even in large queries.
  We no longer report the total number of matches.
- packageReferrers now also uses AfterTypeCheck hook and streaming.
- XML support has been dropped.
- The -format flag has been replaced by -json.

JSON protocol changes:
- The enclosing Result struct has been removed.
- Likewise the 'mode' field (since the caller knows it already)
- "freevars" and "referrers" now emit a stream of objects
  In the case of referrers, the first object has a different from the rest.
- The "referrers" results include the text of the matching line
  (parity with -json=false)

Implementation details:
- the concurrency-safe q.Output function can be called
  many times, each with a queryResult to print.
- fset is no longer saved in Query (cleaner)
- queryResult methods renamed PrintPlain, JSON

2336c53cf0 cmd/guru: compute referrers as packages are type checked
This CL makes little observable difference to the behavior but paves the
way for streaming 'referrers' and (later) 'implements' queries which
scan the entire workspace, but print each result as soon as it is found.

The go/loader package now exposes a hook, AfterTypeCheck, that lets
clients inspect each package as soon as it is type-checked, and also
modify it, for instance to release unneeded data structures.

A 'referrers' query applied to an exported object must scan the entire
workspace.  It uses this hook so to gather uses of the query object in
streaming fashion.  However, for now, it still accumulates the results
and prints them all at the end, though I propose to change that in a
follow-up.

Code details:
- The referrers logic had a 2-iteration loop to load first the query
  package and then if necessary the enlarged program.  The second
  iteration has now been unrolled and split into globalReferrers.
- Queries for package names (whether in a package declaration or
  a qualified identifier) have been split off into packageReferrers.
  It now loads all direct importers of the query package,
  which catches some references that were missing before.
  (It used to inspect only the forward dependencies of the query
  package.)

Also:
- Referrers.Pos (the position of query identifier) was removed from the
  JSON output.  It's a nuisance to compute now, and it's already
  absent from the plain output.
  (In a follow-up, I plan to simplify the information content of the
  JSON output exactly what is currently printed in the plain output.)

2327a65811 cmd/guru: fix tests
A consequence of CL 19747 was that ad hoc packages of a single filename
are no longer valid -scope arguments, which broke most of the tests.

This CL fixes the tests by extracting the import path from the filename.
The test output now includes the import path, not the package
name, of each of these packages, so the output was updated too.

Also, the -scope argument caused the main package to be imported twice,
once as main.go and once under its import path, causing duplicate
'implements' results.

I'm not sure how I failed to notice this.

bf084ef758 imports: add support for vendor directories
Editor modes that invoke the goimports command on temporary copies
of actual source files will need to invoke goimports -srcdir now to say
where the real source directory is. Otherwise goimports will not consider
vendored or internal packages when looking for new imports.

In lieu of a test for cmd/goimports (because it has no tests),
a command transcript:

	$ cd /tmp
	$ cat x.go
	package p
	var _ = hpack.HuffmanDecode
	$

	$ GOPATH= goimports < x.go
	package p

	var _ = hpack.HuffmanDecode
	$ GOPATH= goimports x.go
	package p

	var _ = hpack.HuffmanDecode
	$

But with the new flag:

	$ GOPATH= goimports -srcdir $GOROOT/src/math < x.go
	package p

	import "golang.org/x/net/http2/hpack"

	var _ = hpack.HuffmanDecode
	$ GOPATH= goimports -srcdir $GOROOT/src/math x.go
	package p

	import "golang.org/x/net/http2/hpack"

	var _ = hpack.HuffmanDecode
	$

The tests in this CL and the above transcript assume that
$GOROOT/src/vendor/golang.org/x/net/http2/hpack exists.
It did in 40a26c9, but it does not today.
It will again soon (once Go 1.7 opens).

For golang/go#12278 (original request).

d0c9d43af1 bundle: new docs, command-line interface
Before, "bundle -help" printed only one not particularly useful line:

	Usage of bundle:

and "bundle" printed a bit more but not a standard usage message:

	bundle: Usage: bundle package dest prefix

	Arguments:
	 package is the import path of the package to concatenate.
	 dest is the import path of the package in which the resulting file will reside.
	 prefix is the string to attach to all renamed identifiers.

And most of that output belonged in (but was missing from) the doc comment,
which leaned heavily on the reader inferring usage from one example.

While fixing all this, I ended up dropping "dest" and "prefix" as required
arguments: perfectly good defaults can be inferred in the common case
where the bundle is intended for the current directory. The defaults can be
overridden with the new -dst and -prefix option.

I corrected a TODO about not assuming the package name could be
derived from the destination import path. Like -dst and -prefix, the
default package name can be inferred from the current directory,
but there is also a new -pkg option to override the default if needed.

I added a -o option to specify the destination output file (standard output
is still the default output). One benefit of -o is that it makes the bundle
commands self-contained in the sense of not needing a shell.
That in turn makes them suitable for use with "go generate", so when -o
is specified the bundle output now includes a "//go:generate" comment
for updating the bundle mechanically.

To keep bundle working for net/http's use case, I added a -importmap
option to specify additional import rewrites (net/http needs the http2
import of golang.org/x/net/http2/hpack rewritten to begin with internal/golang.org).

The net effect of all of this is that the first two lines at the top of
net/http/h2_bundle.go will change from:

	// Code generated by golang.org/x/tools/cmd/bundle command:
	//   $ bundle golang.org/x/net/http2 net/http http2

to

	// Code generated by golang.org/x/tools/cmd/bundle.
	//go:generate bundle -o h2_bundle.go -prefix http2 -import golang.org/x/net/http2/hpack=internal/golang.org/x/net/http2/hpack golang.org/x/net/http2

and net/http's copy of http2 can now be updated by "go generate"
instead of by copying and pasting commands from source code to shell.

For an experiment I am doing with cmd/dist bundling archive/zip,
the header is even shorter and makes a better demonstration of the
power of the defaults:

	// Code generated by golang.org/x/tools/cmd/bundle.
	//go:generate bundle -o zip.go archive/zip

New usage message, printed by "bundle -help" and "bundle":

	Usage: bundle [options] <src>
	  -dst path
	    	set destination import path (default taken from current directory)
	  -import map
	    	rewrite import using map, of form old=new (can be repeated)
	  -o file
	    	write output to file (default standard output)
	  -pkg name
	    	set destination package name (default taken from current directory)
	  -prefix p
	    	set bundled identifier prefix to p (default source package name + "_")

See CL for new doc comment.

Following this CL I will send a CL updating the two-line header in net/http/h2_bundle.go
to match the new usage of the bundle, whatever that ends up being.

  or go/ast.Object.
- guessImportPath: make importPath=="" result an error,
  since you can't import the empty string.  Simplify importQueryPackage.

608d57b3ae cmd/guru: call{ers,stack}: avoid pointer analysis where possible
As an optimization, the callers and callstack queries now avoid the
relatively costly pointer analysis in some common cases:

The callers of a function that is never address-taken can be enumerated
directly from the SSA representation.

Similarly, the callstack can be computed initially by ignoring dynamic
call edges; we run the pointer analysis only if no path is found in this
partial callgraph.  As a bonus, this also causes the tool to
preferentially report all-static callpaths.

A callers query on fmt.Errorf now completes in 3 seconds instead of 8,
and a callstack query completes in 2 seconds instead of 8.

The new code is covered by the existing tests.

ce967854d3 cmd/tip: move side health check to main health check. Use 503.
500 is considered to be healthy. Use 503 instead, so the instance is
considered unhealthy while the side is coming up.

Add some extra log statements that help debug instances from
application logs.

Fixes golang/go#13682.

542ffc7e75 tools: switch to standard go/types at tip
A few files have been forked and tagged "go1.5,!go1.6" to work around
minor API changes between the two types packages:
- constant.Value.String() in oracle/describe.go and its tests;
- constant.ToInt must now be called before constant.Int64Val.
- types.Config{Importer: importer.Default()} in a number of places
- go/types/typeutil/import_test.go uses lowercase names to avoid 'import "C"'.

Files in go/types/typesutil, missing from my previous CL, have been
tagged !go1.5; these files will be deleted in February.

All affected packages were tested using 1.4.1, 1.5, and ~1.6 (tip).

This change will ensure that the tree continues to work with go1.4.1.

All files continue to depend on golang.org/x/tools/go/types, but in a
follow-up change, I will switch the primary files to depend on the
standard go/types package.  Another (smaller) set of files will be
forked and tagged, this time !1.6, due to API differences between the
two packages.

All tests pass using 1.4.1, 1.5, and ~1.6 (tip).

a25a8d567b tools/cmd/vet: Create vet checks for examples.
In spite of https://blog.golang.org/examples and
http://golang.org/pkg/testing/#pkg-examples, a number of internal Go
authors have found writing documentation examples to be problematic in
the sense that the syntax is error-prone due to loose coupling with
identifiers found in the source corpus.

This commit introduces a suite of validations for documentation
examples:

    Overall:
    - Correct suffices, if present
    - Niladic function argument and return signatures

    func Example() {}
    func ExampleF() {}
    - F exists
    func ExampleT() {}
    - T exists
    func ExampleT_M() {}
    - T exists
    - M exists within T

Further, if the example is in `package foo_test`, vet attempts to
resolve the respective lookups in `package foo`, if `package foo`
exists (cf., `package stringutil_test`).

7d75e8b219 cmd/fiximports: a tool to rewrite import paths to match import comments.
fiximports enumerates the set of packages identified by the
command-line arguments, using "go list" notation.  Within each
package, it replaces all imports of non-canonical packages by their
canonical name, introducing an import renaming if (heuristically)
necessary.

If a package comes from one of the -baddomains, and it has no import
comment, fiximports reports an error.  The error message includes the
list of packages that import the errant package, directly or
indirectly.  This flag is used to indicate "sinking ship" package
hosting domains like code.google.com.

Caveat: this process is not trivially reversible.  Consider a package A
to which we add an import comment "B", and run the tool.  Package C,
which imported A, now imports B.  ('go get -u' would fetch package B).
But changing the import comment in directory A and re-running the tool
will not cause C to be changed because it no longer imports A; it
imports B.

+ Tests.

Usage:

You can also specify a number of parallel processes with -p flag;
instruct the utility to not kill hanged processes for gdb attach;
or specify the failure output you are looking for (if you want to
ignore some other episodic failures).

Do you find it useful?

9c57c19a58 go/loader: eliminate ImportFromBinary option and PackageCreated hook
The loader package now loads, parses, and type-checks a whole program
from source, and that is all.

Also:
- simplified loader logic
- ssa.Create is gone; use ssautil.CreateProgram.
- ssautil.LoadPackage renamed to BuildPackage.
  It is now independent of go/types' Import hook and the Packages map.
- ssadump: -importbin flag removed.
  The value of this flag was that it caused the tool to print IR
  for only a single package; this is now the normal behaviour.

b28839e4bd oracle: several major improvements
Features:

  More robust: silently ignore type errors in modes that don't need
  SSA form: describe, referrers, implements, freevars, description.
  This makes the tool much more robust for everyday queries.

  Less configuration: don't require a scope argument for all queries.
  Only queries that do pointer analysis need it.
  For the rest, the initial position is enough for
  importQueryPackage to deduce the scope.
  It now works for queries in GoFiles, TestGoFiles, or XTestGoFiles.
  (It no longer works for ad-hoc main packages like
  $GOROOT/src/net/http/triv.go)

  More complete: "referrers" computes the scope automatically by
  scanning the import graph of the entire workspace, using gorename's
  refactor/importgraph package.  This requires two passes at loading.

  Faster: simplified start-up logic avoids unnecessary package loading
  and SSA construction (a consequence of bad abstraction) in many
  cases.

  "callgraph": remove it.  Unlike all the other commands it isn't
  related to the current selection, and we have
  golang.org/x/tools/cmdcallgraph now.

Internals:

  Drop support for long-running clients (i.e., Pythia), since
  godoc -analysis supports all the same features except "pointsto",
  and precomputes all the results so latency is much lower.

  Get rid of various unhelpful abstractions introduced to support
  long-running clients.  Expand out the set-up logic for each
  subcommand.  This is simpler, easier to read, and gives us more
  control, at a small cost in duplication---the familiar story of
  abstractions.

  Discard PTA warnings.  We weren't showing them (nor should we).

  Split tests into separate directories (so that importgraph works).

68b5f7541d cmd/oracle: usability improvements to "describe", "referrers"
Emacs integration:
- eliminate oracle minor mode
- in go-mode, bind F5, F6 to "describe", "referrers".
  This reverts a previous policy decision but convenience matters too.
- don't insist on an analysis scope for modes that don't do PTA.
- don't hide the filename as "▶"; show the last 20 chars.
  (Especially useful for "referrers" mode.)
- output postprocessing: don't get stuck in a loop if the output
  is not as expected (e.g. when it includes a panic log).

referrers:
- show the matching lines (like grep does).

    Also: redesign the tests and add many new cases.

	lo := uint8(0)

c6ec5ea66d cmd/gorename: support renaming of methods with consequences for other types, iff initiated at an abstract method.
Previously, gorename rejected all method renamings if it would
change the assignability relation.

Now, so long as the renaming was initiated at an abstract
method, the renaming proceeds, changing concrete methods (and
possibly other abstract methods) as needed.  The user
intention is clear.

The intention of a renaming initiated at a concrete method is
less clear, so we still reject it if it would change the
assignability relation.  The diagnostic advises the user to
rename the abstract method if that was the intention.

Additional safety checks are required: for each
satisfy.Constraint that couples a concrete type C and an
interface type I, we must treat it just like a set of implicit
selections C.f, one per abstract method f of I, and ensure the
selections' meanings are unchanged.

The satisfy package no longer canonicalizes types, since this
substitutes one interface for another (equivalent) one, which
is sound, but makes the type names random and the error
messages confusing.

Also, fixed a bug in 'satisfy' relating to map keys.

+ Lots more tests.

See the usage message in main.go for orientation.

To the best of my knowledge, the tool implements all required
soundness checks, except:
- the dynamic behaviour of reflection is obviously undecidable.
- it rejects method renamings that change the "implements" relation.
  It should probably be more aggressive.
- actually it only checks the part of the "implements" relation
  needed for compilation.  Understanding the dynamic behaviour
  of interfaces is obviously undecidable.
- a couple of minor gaps are indicated by TODO comments.

Also:
- Emacs integration.
- tests of all safety checks and (some) successful rewrites.

6c93dbff3e go.tools/godoc: deal with fallout from $GOROOT/src/pkg -> $GOROOT/src renaming.
To avoid breaking URLs, we redirect /src/pkg/* to /src/*.

The URL /pkg is now the "directory" /src, which triggers the
"Packages" index.

All other references to "src/pkg" are now gone,
except a number in the namespace documentation which are
probably still illustrative.

Tested: go test cmd/godoc godoc
        Manual inspection of src and src/pkg pages.
        with GOROOT and GOPATH packages
        -analysis
        /AUTHORS file URL still works
